GENERAL INFORMATION

To the Purchaser:

Congratulations! You are the owner of one of the ﬁ nest

pumps on the market today. Burks® Pumps are products

engineered and manufactured of high quality components.

Over eighty years of pump building experience along

with a continuing quality assurance program combine

to produce a pump which will stand up to the toughest

pumping projects.

This manual will provide helpful information concerning

installation, maintenance, and proper service guidelines.

Receiving:

Upon receiving the pump, it should be inspected for

damage or shortages. If damage has occurred, ﬁ le a claim

immediately with the company that delivered the pump.

If the manual is removed from the crating, do not lose or

misplace.

Storage:

Short Term - Burks Pumps are manufactured for efﬁ cient

performance following long inoperative periods in storage.

For best results, pumps can be retained in storage, as

factory assembled, in a dry atmosphere with constant

temperatures for up to six (6) months.

Long Term - Any length of time exceeding six (6) months,

but not more than twenty four (24) months. The units

should be stored in a temperature controlled area, a roofed

over walled enclosure that provides protection from the

elements (rain, snow, wind blown dust, etc..), and whose

temperature can be maintained between +40 deg. F and

+120 deg. F.

If extended high humidity is expected to be a problem, all

exposed parts should be inspected before storage and all

surfaces that have the paint scratched, damaged, or worn

should be recoated with a water base, air dry enamel paint.

All surfaces should then be sprayed with a rust-inhibiting

oil.

INSTALLATION

1. Wet return line should be connected to the tapping in

the receiver tank.

2. Strainer/Dirt Trap should be installed in the return line

immediately before the receiver tank.

3. Check Valve should be installed between the boiler and

the pump.

4. Vent to atmosphere from tapped opening in the top of

the tank using 1" line or larger. Do not use valves or

traps in the vent line. A tee in the vent line, connected to

a drain, will direct overﬂ ow water to drain in case of a

pump failure.

WARNING - The receiver tank is NOT a

pressure vessel. It MUST be vented to

atmosphere to prevent pressure build-up.

Any internal pressure other than that due to

the weight of ﬂ uid in the tank IS UNSAFE -

Warranty is void if receiver tank is pressurized.

5. Float Switch or Mechanical Alternator should be wired

by competent electrician to insure proper performance

of the motor. Before wiring, make certain the voltage

and cycles of the supply circuit are the same as on

the motor nameplate. Refer to wiring diagram on motor

nameplate and on switch tag. Controls are factory set

for speciﬁ c ﬂ oat travel. Float travel may be adjusted for

close control of receiver water level. See attached tag

for detailed instructions.

OPERATING

1. Open all valves in return line and discharge line to boiler.

2. Apply electrical power to system.

When water level in receiver tank reaches proper level,

ﬂ oat switch or alternator will actuate pump motor to

return condensate to boiler.

MAINTENANCE

LUBRICATION

No lubrication is required for the liquid end of the pump.

Motors are equipped with ball bearings which are grease-

packed and sealed at the factory. No additional lubrication

is required.

Steam Traps should be carefully checked and kept clean.

Live steam escaping from receiver tank vent indicates

faulty operation of trap.

Strainer/Dirt Trap should be cleaned twice yearly, or

oftener if required. Remove cap and screen and ﬂ ush out

trap body.

Tank Drain - Tank should be drained at the end of each

heating season by removing drain plug located below

return line connection. Do not expose unit to freezing

temperatures when it contains water.

CAUTION - Boiler Compound should NOT

be introduced into the system through the

receiver tank, but added on the discharge side

of the pump by means of a commercial injector

designed for that purpose. This will prevent

wear or clogging caused by certain types of

boiler compounds which do not completely

dissolve.

If it should be necessary to contact your BURKS dealer,

distributor, or the factory regarding your Series GV

Condensate Return System, always give the Catalog

Number and Serial Number found on the pump nameplate.
